About unlimited Currents
Unlimited mode deals a fresh Currents board every time you load the page or press New puzzle — no calendar, no cap, just another grid of numbered gates waiting for one clean line. Boards lean toward the satisfying middle of the size ladder, with the occasional small warm-up or full-size 7×8 challenge, and every one is generated and verified to have a full-cover route that meets its gates in order.
Because unlimited boards are not dated, they are the pressure-free place to practice: rehearse the rules on the how to play page, then drill the strategy guide's habits — forced corners first, parity checks between gates, never sealing a pocket — until they are reflexes. Every board's address bar carries a seed link you can share, so a friend can race the exact same river. When you are ready for the one that counts toward your streak, head back to today's daily puzzle.
